Estudo de metodologia de avaliação de risco a escorregamento de terra em área urbana : o caso do município de Juiz de Fora - MG

Abstract

A significant number of Brazilian cities, as well as the city of Juiz de Fora, Minas Gerais, has faced serious problems in recent years for landslides on slopes, including causing the death of several people. To manage this situation has been prepared by the municipality of Juiz de Fora a "Mapping Areas at Risk", supposedly guided by the methodology proposed by the Ministry of Cities. This mapping has made the identification of forty-two areas of high and very high risk, and eight critical areas highlighted that in addition to being classified as high and very high risk, are occupied by slums. The objective of this study is to understand and analyze in detail the criteria used in the mapping done for the city of Juiz de Fora, from the study of the methodology used to evaluate the risk of landslides. After an extensive literature review on the subject were conducted field visits, data collection and filings with the Civil Defense of the municipality, for the analysis of the technical-scientific mapping of the risk, which led this work to suggest changes and updates in this "mapping". Were studied with a further deepening the eight risk areas identified as priorities, outlining the criteria used for awarding the degree of probability of risk. A critical evaluation is performed in the results obtained in evaluating the consequences of that degree of probability of risk.
